To LZ whom v-mayco7tcernfor the vinsertion of the finger of the operator, Be it known that I, VALENTINE ZWISSLER, wherefrom it will be seen that as the lever 9 a citizen of the United States, residing in the yis raised and lowered the spindle and its city and county of Philadelphia, State of adjuncts will move in unison therewith. 55 5 Pennsylvania, have inventedjanew and usel'designatesa flattened face or portion of ful Improvement in -Stapling Machinesof the spindle 5, to Athe ,lower portion of which which thefollowing isa specification. is securedthe spring 14, the latter consisting My invention consists of an improved couof the upright curved member 16,which'is struction of a stapling machine wherein deilected downwardly at the point 17 to form 6o Io means are provided for rendering the stapling the limb 18, which isolt'set rearwardly from devices temporarily inoperative in case the the main portion 16 thereof, as seen in Fig. machine becomes clogged, provision being 1, and is bent at the point 19 and deflected .made for providing access to the stapling upwardly to form the member'20.

It will, however,` be apparent that as each staple is fed to its, extreme forward position it will be directly under the clenching device 25, the latter consisting of a blade attached to thespindle 5 and being adapted to io contact with astaple during the actof clenching the same, as will be understood from Fig. In case a staple becomes bent or broken or assumes such a position as to clog the clenching device and thereby render the same i5 temporarily inoperative it is very desirable that means be provided so that access may be had to the staples and clenchiug mechanism. To effect this, I have provided the outer extremity of the arm 4 with a cap 26, which is zo hinged at the pointv 27, the said cap being provided with an ear 23, which is adapted to be secured to the stationary ear 29 by the screw or other fastening devices 30, so that in case the clenching device becomes stuck Yz5 or inoperative by reason of a broken or improperly-bent staple upon the removal of the screw 30 the cap 2G can be swung into the position seen in Fig. 5 and the parts rendered readily accessible for the purposes of inspec- 30 tion or repairs.

The cap 2G is provided with ways 31, which serve to guide the clenching device 25 in its reciprocations and also as a chamber for the reception of the staple, which has been propelled to its extreme forward position.

In order that the staples may be clenched in a uniform manner, I provide in addition to the clenching device an adjustable gage or table, the same consisting of the laterally-ex- 4o tending portions 32 and the upwardly-extending abutments 33, against which the paper to be stapled is placed, said portions 32 and 33 being carried upon the arm 34, which is prolonged to form the base portion 35, having the slot 36 therein, through which passes the screw 37, whereby the abutment 33 can be moved toward or away from the stapling devices, according to requirements.

In the operation of the machine the arm 4 5o can be readily raised and lowered by the insertion of a iinger of the operator in the eye 12, it being apparent that when the arm assumes the position seen in Fig. 1 the eye l2 of the lever 9 may be depressed and the spindle 5 and its adjuncts will assume the position seen in Fig. 4, the portion 19 of the spring 14 moving upwardly Yfrom the position seen in Fig. 3 to the position seen in Figs. 4and 5, and the staple having been propelled for- 6o wardly into the recess or chamber 3l and the clenching device 25 having been depressed by a blow upon the head 6 it will be apparent that the staple will be clenched when the parts assume the position seen in Fig. 3.

It will be apparent from an inspection of Fig. 3 when the spindle 5, carrying the spring and its adjuncts, is raised from the position seen in Fig. 3 to the position seen in Fig. 4, the right-hand portiou'ot' the member 18 of the spring will ride around the pin 21, so that 7o when the spindle 5 and the stapling devices are in their highest position the portion 19 will bc slightly in contact with the pin 2l, anda blow on the head 6 will effect the clenching of the staple when the parts assume the position seen in Fig. In case, however, an improper number of staples are presented to the stapling device, or in case the staples be come clogged within the cap or staple-case 2G, the stapling'devices will become locked in the position seen in Fig. G, wherein the extremity 20 ofthe member 2O will be in contact with the pin 2l, an upward movement of the spindle and its stapling devices from the position seen in Fig. 6 to the position seen in 85 Fig. 4 will be prevented, a downward movement of the stapling device being prevented by the clogging of the staples within the cap 26. The operator then by opening the cap 26 into the position seen in Fig. 5 can ascer- 9o tain the cause of the trouble and remedy the same,- whereupon by depressing the parts from the position seen in Fig. G to the position seen in Fig. 3 the stapling devices can be readily elevated, as indicated in Fig. 4. In other words, it is necessary for the spindle 5 and its adjuncts to make a complete upward and downward stroke iu order to properly permit the feeding and clenching of the staples.

It will be apparent that the contour of the spring 14 can be slightly changed according to requirements, and that other equivalent devices therefor may be employed without departing from the spirit of my invention, which consists, broadly, in providing stapling devices with a temporary locking device, as above explained, whereby the operator is enabled to ascertain and remove the cause of the trouble should any exist.

By loosening the screw 37 and moving the arm 34, carrying the abutments 33, toward or away from the clenching device the device can be adjusted so that the staples will appear in uniform relative positions. In case the stapling device becomes stuck or clogged the parts are readily accessible for the purpose of inspection and repairs upon loosening of the screw 30, whereupon the cap 26 can be swung into the position seen in Fig. 5, as 12o has been explained.

It will be apparent that various changes may be made by those skilled in the art, which will come within the scope of my invention, and I do not, therefore, desire to be limited in every instance to the exact construction herein shown and described.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a stapling-machine, an arm pivotally supported, a spindle movable in said arm, a pin secured in fixed position in said arm, and a spring normally curved and haviuga bend IIO intermediate its ends Aand a bend at its upper end, and a'spring member with a stop-shoulder intermediate said bends, said spring be'- ing carried upon said spindle and adapted to coact with said pin, whereby said spindle is prevented from upward movement during its ascent whenever clogging of the staple occurs and also locked in its downward movement.

2. In a stap1ing-machine,an arm pivotally supported, a spindle vertically movable in said arm, and having a lattencdportion, a normally curved springv secured upon said spindle in proximity to said flattened portion, said spring consisting of the 'member 16'def flected downwardly at the point 17 to form the member 18, the latter being bent upon itself intermediate the ends of the spring and deiiected upwardly at the point 19 to form point 17`to form the member 18, the latter b eing deilected upwardly at the point 19 to` form the member 20, in alinement with .the member 18, a pin secured in fixed position and adapted to coact with said spring and a clenching device carried by said spindle.
